But just at this moment General Buckner's brigades come out of their intrenchments. They pass in front of their rifle-pits at the base of the hill, and march rapidly down to the Dover road. Colonel Wallace sees them. In a few minutes they will pour their volleys into the backs of his men. You remember that the Seventeenth and part of the Forty-ninth Illinois regiments were left standing near the road. You hear from their muskets now. They stand their ground and meet the onset manfully. Two guns of Taylor's battery, which have been thundering towards the south, wheel round to the northeast and sweep the Rebels with grape and canister. Three fourths of the Rebel army is pressing upon McClernand's one division. His troops are disappearing. Hundreds are killed and wounded. Men who carry the wounded to rear do not return. The Rebels see their advantage, and charge upon Schwartz's and McAllister's batteries, but are repulsed. Reinforced by new regiments, they rush on again. They shoot the gunners and the horses and seize the cannon. The struggle is fierce, but unequal. Oglesby's men are overpowered, the line gives way. The Rebels push on with a yell, and seize several of Schwartz's and McAllister's guns. The gunners fight determinedly for a moment, but they are few against many, and are shot or taken prisoners. A Mississippi regiment attempts to capture Taylor's guns, but he sweeps it back with grape and canister. Up to this moment Wallace has not yielded an inch. Two of Oglesby's regiments next to his brigade still hold their ground, but all who stood beyond are in full retreat. The Rebels have picked off a score of brave officers in Oglesby's command,--Colonels Logan, Lawler, and Ransom are wounded. Lieutenant-Colonel White of the Thirty-first, Lieutenant-Colonel Smith of the Forty-eighth, Lieutenant-Colonel Irvin of the Twentieth, and Major Post of the Eighth are killed. The men of Oglesby's brigade, although they have lost so many of their leaders, are not panic-stricken. They are overpowered for the moment. Some of the regiments are out of ammunition. They know that reinforcements are at hand, and they fall back in order. To understand Wallace's position at this stage of the battle, imagine that you stand with your face towards the south fighting a powerful antagonist, that a second equally powerful is coming up on your right hand, and that a third is giving heavy blows upon your left shoulder, almost in your back. Pillow, with one half of his brigades, is in front, Johnson, with the other half of Pillow's command, is coming up on the right, and Buckner, with all of his brigades, is moving down upon the left.
